Abstract: A method for modulating angiogenesis in a cancer or tumor refractory to anti-VEGF, including identifying a cancer cell as being referactory to anti-VEGF, and then contacting the cancer cell refractory to anti-VEGF with an effective amount of an agent that modulates interaction between Gal1 or a Gal1 fragment and the natural binding partner of Gal1 or the Gal1 fragment to thereby modulate angiogenesis.

Abstract: Process for obtaining lithium compounds and intermediate compounds, comprising the following steps: a) contacting aluminosilicate particles, for example ?-spodumene, with at least one fluorine compound, for example HF, NaF or others; b) stirring the mixture increasing the temperature until reaching an appropriate temperature; c) carrying out at least a precipitation and filtration process of the mixture of step b), and, d) recovering the lithium compound. The process may comprise using HF at a concentration between 5 and 30% v/v or NaF at a concentration between 5 and 30% w/v; a solid/liquid ratio of step a) between 0.9 and 14.4% w/v; a particle size of between 29 and 200 ?m. The final lithium product of the process may be lithium carbonate or lithium fluoride.

Abstract: A device for diagnosis of physiologic status and/or selection of best spermatozoa of a semen sample based on chemotaxis, and the procedure of thereof, enabling by a simple and inexpensive device the diagnosis and selection of the best spermatozoa in only one step. Only needed are: the present device, a regular light microscope, and personnel with elementary knowledge of laboratory management. The device is of the type having two communicated compartments (1a, 1b), and where said compartments (1a, 1b) communication occurs through a duct or bridge (2) located in the lower part, and above the lower level of mentioned compartments (1a, 1b); in the entrances of said compartments (1a, 1b) appropriate closing means (3, 4) and appropriate air output ducts (5) are placed communicating the top end of compartments (1a, 1b) with the exterior.

Abstract: The invention provides promoters inducible by reactive oxygen species (ROS), capable of driving the expression of a gene of interest, particularly in a tumor cell. More particularly, it refers to promoters inducible by reactive oxygen species, that may be used to drive the expression of a gene of interest, such as a therapeutic gene, or a reporter gene for use in image diagnosis. The promoters comprise at least a fragment of a promoter sequence responsive to said reactive oxygen species, and corresponding to a gene highly expressed in cancer cells, wherein the fragment of the promoter sequence responsive to reactive oxygen species (ROS) is selected from the group of: the VE element of the VEGF promoter, the E6 element of the promoter of the EGR-1 gene, the MMP-1 element and a chimeric promoter containing an E6 element and a VE element. It also provides vectors carrying a human therapeutic or non therapeutic gene of interest, operably linked to said promoter sequence and compositions comprising the same.

Abstract: Brassinosteriods, illustrated by the following exemplary compounds, are disclosed: The compounds have anti-inflammatory and antiviral activity. In pharmaceutical compositions, the compounds are useful in ophthalmic pharmaceuticals for treatment of diseases caused by adenovirus, such as epidemic keratoconjunctivitis, and herpes simplex type 1, such as herpetic stromal keratitis.

Abstract: The system records the movement of tiny organisms housed in closed micro plates traversed by an infrared beam generating a signal as a function of the diffraction caused by the body of the microorganism. The behavior detection procedure includes processing the diffraction signal to discriminate the locomotor activity of the microorganism. The system may be used in the chronobiological field, longevity, toxicity, and pharmacology studies.

Abstract: A passive stream regulating system applicable to air-flue gas or water-flue gas heat exchangers, preferably natural gas balanced flue or natural flue home heaters and home boilers, which allows to attain non-over oxygenated stoichiometric mixture conditions. The system is included by small diameter tubes or other geometric systems formed by small channels, to produce a strong laminarization of the aerodynamic flow established within the venting tube, which are located in sections of the conduit or passage of incoming cold air to the combustion chamber of the exchanger or in sections of the conduit or passage of hot flue gases released to the environment.
